1.【生化】组蛋白
1.a simple protein bound to DNA, involved in the coiling of chromosomes.
1.and the DNA is wrapped around the histones like a few wraps of thread around a spool.
而DNA就像是一些缠绕在线轴上的线一样,缠绕在组蛋白周围。
2.Sometimes a physical gap where the DNA floats free of any histones can halt the spread, Bi says.
毕鑫说,有时DNA上会有一段完全没有组织蛋白的实质缺口,可以阻挡传递的进行;
3.Chromatin contains half as much DNA as it does protein, most of which is in the form of histones .
染色质当中DNA与蛋白质的数量约各占一半,后者大多以组织蛋白的形式存在。
4.Histones are protein- found in eukaryotic cell nuclei, tightly bound to DNA, which has many phosphate groups.
组蛋白是存在于真核细胞核中的与含很多磷酸基团的DNA紧密结合的蛋白质。
5.Histones also play a role in turning genes on so that their coded instructions can be copied and sent to other parts of the cell.
组蛋白还起到了基因开关的作用,因此它们编码的信息可以被复制并且传递到细胞的其它部位。
6.Epigenetic marks, such as the modifications of the histones, are also important for the specialisation of the body's cells.
表观遗传标记,例如组蛋白修饰,对于机体细胞的分化也很重要。
7.An octa-mer of histones package DNA into a structure called a nucleosome.
一种组蛋白的八聚物把DNA打包成一种叫做核小体的结构。
8.MOTIVATION: Post-translational modifications to histones have several well known associations with regulation of gene expression.
动机:组蛋白翻译后修饰与基因表达调控具有一些众所周知的相关性。
9.A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones).
一条染色体是由遗传物质(一长段DNA)及包裹其周围的结构支持蛋白(组蛋白)组成。
10.This epigenetic information can be introduced by cytosine methylation and by marking nucleosomal histones.
这种表观遗传信息可以介绍的胞嘧啶甲基化和组蛋白标记核小。
